Signs for overhead power lines are essential for communicating safety information and are typically classified by the level of hazard they represent. Common types include:

• Danger Signs (Red): These indicate an immediate and serious hazard that will result in death or severe injury if not avoided. They are used for high-voltage lines and critical areas.

• Warning Signs (Orange): These warn against a potential hazard or unsafe practice that could result in death or serious injury.

• Caution Signs (Yellow): These warn against a potential hazard that could result in minor or moderate injury. They are often used to caution against practices that could lead to property damage.

For enhanced safety, signs often include clear pictographs and concise messaging like "High Voltage," "Look Up," or "Keep Clear."
